What it does
Gravity Forms is a paid WordPress form builder with conditional questions, file uploads, payment connections and workflow integrations. Its annual licences differ in site count and included add-ons. It has no free version; a separate online demo lets you explore the software.
Collect the right supporting files
Gravity Forms' File Upload field gives a document-collection form several separate controls:
- Add File Upload from the form editor's Advanced Fields.
- Set the allowed file extensions for the documents you need.
- Choose whether the field accepts one file or multiple files.
- Set the maximum size allowed for each file.
For a project brief, those choices distinguish a single reference PDF from a batch of supporting images. Uploaded files are part of the submission workflow on the WordPress site. Use conditional fields or pages when only some requests need the supporting material.
The upload field checks file count as well as individual file size. If a multiple-upload submission exceeds the maximum count, all files are rejected and one error is shown.
Choose the required add-ons
| Annual licence | Sites | Included examples |
|---|---|---|
| Basic | 1 | HubSpot, Mailchimp and other basic connections |
| Pro | 3 | Stripe, Dropbox, Zapier and Slack |
| Elite | Unlimited | Surveys, signatures, partial entries and user registration |
Buy a licence through the Gravity account checkout, then install the plugin on WordPress. There is no trial version to install on your own site, but the official online demo is available before purchase.
